♦ Notes on pattern designing

1 Place VCC pin (pin 6) and VIN pins (pin 11 and 12) lines separately and use an input capacitor (+) for connection.

2 Place GND pin (pin 5) and A pin (pins 7 and 8) lines separately.

3 Connect A pin (pins 7 and 8) with the input capacitor (–) through a Ferrite-bead core.

4 Connect GND pin (pin 5) with the input capacitor (–) or the output capacitor (–). However, connect with the

output capacitor (–) unless otherwise specified.

5 Shorten the length of the line between the input capacitor (–) and the output capacitor (–) as well as possible.

6 Connect VS pin (pin 2) with the output capacitor (+).
